Abstract

A communication system has outbound information in the form of multi-bit messages is carried by cyclic waveforms (11) over an electric power distribution network. The signal is detected independently at any of a plurality of locations remote from the source by obtaining signal data through sampling of the cyclic waveform over a predetermined portion of successive cycles.
The predetermined portion is divided into a plurality of predetermined ranges. From a predetermined number of bits at the start of each message, the particular predetermined range which contains the greatest signal strength is selected. For the remaining bits of the message, only those samples in the selected range are analyzed to detect the outbound message. To reject cross-talk, preselected ranges in which cross-talk signals are likely to appear are monitored, and in-phase messages are rejected when the signal strength in the in-phase range is less than the signal strength in at least one of the cross-talk ranges.
